input: Add ANSI 3.64 escape sequence generation.
To support Non-ASCII keys (ex, Fn, PgUp/Dn, arrow keys, ...), we need to translate key code into escape sequence. (Updated by to move away from a function to store keycodes, so we can easily record how many were sent. We now need to return this from input_send_keycodes() so we know whether keys were generated.)
